ERS-1上的微波辐射计有23.8和35.6千兆赫的两个通道。它是一个天底指向传感器，目的是校正高度计对流层路径延迟。仪器的特点进行了说明，并建立其性能从地面校准结果。使用发射后获得的早期数据，在飞行中的工程校准，表明辐射计的行为是标称的。增益稳定性允许噪声降低，和辐射计的性能似乎是指定的一样好。>
The microwave radiometer onboard ERS-1 has two channels at 23.8 and 35.6 GHz. It is a nadir pointing sensor, which is aimed at the correction of the altimeter tropospheric path delay. The characteristics of the instrument are described, and its performance is established from ground calibration results. Using early data obtained after launch, the in-flight engineering calibration is presented, showing that the radiometer behavior is nominal. The gain stability permits noise reduction, and the radiometer performance appears to be as good as specified. >
